Sensor Chip CM4

Use when sample contaminants have a high positive charge

	•		Improves sensitivity when monitoring certain interactions
	•		Suitable for negatively charged proteins and nucleic acids
	•		Attach proteins, nucleic acids, carbohydrates or small molecules
	•		Couple to carboxyl groups on the sensor surface via -NH2, -SH, -CHO, -OH or -COOH

Matrix: similar to Sensor Chip CM5 but with a lower degree of carboxymethylation, which can improve sensitivity for certain interactions. Due to the reduced net negative charge, the surface is well suited for use with negatively charged molecules.
